When looking for the best portable air conditioner and heater, a few of the things that you should probably have on your checklist include ease of maintenance, energy efficiency, and cooling power. The Honeywell MM14CHCS checks off all these items, making it one of the air conditioners that you really ought to look into. The Honeywell MN14CHCS air conditioner is available in either black or silver, and has a feather touch control panel that’s very easy to view and adjust. This isn’t the only highlight that you can expect from the air conditioner though. Go ahead and get to the end of this review to find out what else it’s got in store and how it compares to the best-selling air conditioners on the market today.

Why We Like It – Honeywell Portable Air Conditioner

The Honeywell Portable Air Conditioner is a 14000 BTU AC unit that’s powerful enough to keep your 500 to 700 sq ft room warm or cool. It’s got washable, removable filters, and at 55 decibels, guarantees very quiet operation. An even quieter unit is the Honeywell MO10CESWK model which ranges from about 50 to 53 decibels at its highest rating.

  • 3 Fan modes
  • Timer for automated operation
  • Quiet operation
  • No sleep mode or auto restart button


With a 14000 BTU rating, the Honeywell portable air conditioner is easily capable of cooling down a room that’s up to 700 square feet in size, and efficiently warming up one that’s up to 500 square feet large. It’s similar to the Keystone air conditioner in some aspects of cooling. It shares the same working capacity with the ARC-14SH Whynter Portable Air Conditioner, and they both feature four functions in one – air conditioner, dehumidifier, fan, and heat pump. The only feature that we wish the MN14CHCS portable air conditioner had would be a sleep timer and an auto-restart function, but even without, it remains a great choice for an air conditioner. If you need a unit that has a sleep mode operation, then this Honeywell Portable Air Conditioner (10000 BTUs) model is recommendable. However, if you live in an area where an evaporative cooler is effective, check out our Hessaire MC18M Portable review.

Energy Efficiency

The MN14CHCS Honeywell portable air conditioner comes with a timer built in that you can use to have it working only when you need it, and this is key because it’ll help you scale down your energy costs. You can find another built-in timer on a portable model in our Honeywell CO25AE review. You can choose to have it automatically switch on in the evening, or even at midday when it’s hottest outside. The air conditioner’s dehumidifier removes up to 86 pints of moisture in the air for every 24 hours, and with up to three fan modes to choose from, you’ll be able to suit it to your specific needs. if you are in an area where an evaporative cooler is ideal, check out our Luma Comfort EC111B review for another great option.  


The air filters inside the Honeywell portable air conditioner are both easy to remove and easy to clean, so you shouldn’t have any problems with maintenance. The filters keep out any dust or pollen particles, so that the air that you breathe in stays fresh and clean. For a portable unit without a filter, you can read our Icybreeze cooler review.


You’ll get a 1-year limited warranty with the Honeywell AC, and while this may sound brief for most people, the average lifespan for most portable air conditioners stands at about 10 years or more if you take good care of it. Even with the large difference in cooling capacity between it and the LG LP1217GSR, they both have the same 1 year warranty period, as well as a competent customer care team that’ll be keen to help you out in case of any issues.


Honeywell remains one of the most popular Air conditioning brands for anyone who’s looking for a piece of equipment that is well designed, and easy to use. For its price, the MN14CHCS portable air conditioner is quite efficient, and at only 55 decibels, very quiet. Just like the Honeywell MO08CESWK Compact Portable Air Conditioner, it also comes with a remote control for convenient operation, and 4 smooth moving caster wheels to allow for easy movement. Also, check out our LG LP1417WSRSM review for an option that can be controlled from anywhere using WiFi.

Honeywell Portable Air Conditioner Wrap Up

There are so many different types of air conditioners that you can opt for when looking for an HVAC system for your house or office. You can go for a window unit, a central air conditioner, or even a ductless mini-split system, but the only issue with all these is that they’re not portable. The Honeywell MN14CHCS, however, is, so you’ll be able to move it wherever you need to.
